-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Service Monitoring Tool for Virtual Router
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Various services running on the CloudStack virtual routers can be monitored by using a Service Monitoring tool. The tool ensures that
+services are successfully running until CloudStack deliberately disables them. If a service goes down, the tool automatically restarts the service, and if that does not help bringing up the service, an alert as well as an event is generated indicating the failure. A new global parameter, ``network.router.enableservicemonitoring``, has been introduced to control this feature. The default value is false, implies, monitoring is disabled. When you enable, ensure that the Management Server and the router are restarted.
